Özet

Polyaniline (PANI)-coated yarn samples were performed by dip coating method and characterized. Structural and morphological properties were investigated by FTIR and FESEM, respectively. Gas sensor applications of PANI-coated yarns were performed in a uniquely designed gas detection and control system. The usability of PANI-coated yarn samples as gas sensors was evaluated and the performances of different yarn types were compared. Conductivity changes of PANI-coated yarns exposed to CO and NH3 gases were measured and the effects of these changes on gas sensing capabilities were analyzed. In CO gas applications, the responses of PANI-coated yarn samples in 400 ppm, 600 ppm, and 800 ppm were examined and it was determined that the polyamide yarn sample exhibited a significant conductivity increase. In NH3 gas applications, the response times and recovery times of different yarn types in 400 ppm were evaluated and it was observed that cotton yarn sensors had high response times, though acrylic yarn sensors offered fast response times in general. The study demonstrates the potential of PANI-coated different yarn samples as gas sensors for wearable technology.
